Description

Technical Field

[0001] The utility model relates to the technical field of electrical primary equipment monitoring, in particular to an installation structure of an embedded monitoring device for a GIS isolating switch. Background Art

[0002] In recent years, GIS equipment has been widely used in power systems. Compared with conventional open substations, GIS has the advantages of compact structure, small footprint, high reliability, flexible configuration, convenient installation, strong safety, strong environmental adaptability, and small maintenance workload. The maintenance interval of its main components is not less than 20 years. As a device for power system operation, failures may occur during use, and they are somewhat hidden.

[0003] At present, the knife switch of GIS equipment is not open, and its actual position cannot be directly viewed. It is impossible to view the current opening and closing status of the knife switch. It can only be viewed manually through the observation window at the equipment position. When checking the position of the GIS knife switch, it is necessary to shine a light source in one window and observe whether it is in place through the other window. This requires two parts: a light source and a camera. Since the redundant part on the surface of the GIS equipment fixes these two parts, people need to hold them. Moreover, since the observation window is on the tank body and the position is not parallel to the patrol path, personnel need to climb up the GIS bracket when observing, which is very inconvenient. In addition, the observation window is small, and it is difficult to observe the opening and closing position of the knife switch under strong sunlight. On one side, a strong light source needs to be injected, and on the other side, personnel need to observe carefully, which is dangerous for high-altitude operations, and there is no convenient place to wear a safety belt at the observation position. Therefore, the manual observation operation method to check the situation of the knife switch is very unstable, and the monitoring efficiency is low, the operation safety is also low, and the GIS knife switch status data cannot be obtained in real time.
